Как исправить ошибку при создании абстрактного класса пользователя в DJANGO?

Добавил в модель пользователя AbstractUser и после этого слетела регистрация на сайте, выдаёт следующую ошибку при отправлении формы регистрации:
Manager isn't available; 'auth.User' has been swapped for 'mainsite.ProjectUser'

(Логин работает, пользователи создаются в админке, другие модели исправно работают и так далее)
Абстрактного юзера создавал по документации в самом начале проекта без каких-либо миграций.

Якщо абстрактний - спробуй так
